5 oiaims. (oi. 22e- 101) My present invention relates to can packingmachines for packing iiaked fish and similar products into cans.y

One of the principal objects of this invention is to provide a canpacking machine of this class which may be closely regulated formaintaining a desired un'formityl in the amount of fish or otherproducts packed into a can.

Another object of this invention is to provide simple meansof varying'the quantities of fish or other products to be packed into cans.

Another object 'also isk to provide a packing machine of this classwhereby the product to be packed is compressed before and while it istheultimate container or can. A further object of this invention is toprovide a machine of this class for rapidly packing cans, and alsopacking them with a minimum of waste. An object also of this inventionis to provideI a novel, simple, and economical method of packing cans.-5

With these and other objects in view as will appear hereinafter, I havedevised a can packing machine having certain novel features ofconstruction, combination, and arrangement of parts and portions, forpacking aked iish or other products, as will be hereinafter described indetail, and particularly set forth inthe appended claims, referencebeing 'had to the accompanying drawings, and to the characters ofreference.

thereon, which form a part of this application, in which:

Fig. l is a side elevational view of my can Vpacking machine in one formof construction,

portions being broken away lustration; i

Fig. 2 is a transverse 2-2 of Fig'.3;.

Fig. 3 4is a fragmentary front elevational view to facilitate the'ilsectional view taken at Fig. 4 isa fragmentary plan view thereof and,Fig. 5 is a fragmentary sectional view in plan, taken at 4-4 of Fig. 2.

My can packing machine may be mounted` frame l. On top of the frame isturntable which consists of a star lhaving can receiving recesses 2a,

upon a unitary mounted a can feed 4wheel .2, and thereabove a openingsBa'spaced 'edually from each other and the revolution of the turntable.These openings are axially aligned with theirecesses 2a. Below theturntable, and at least at the rear portion thereof, is a can supportconsisting of an open track 4 on which `the cans are carried by theperforated cutter disc 3, having n yit) ' through bevel `shaft is aratchet 53 which is rotated by a pawl rill which meshes lower end of thecylinder is open Above the track and outwardly from the feed wheel is acircular can guide 5, which retains the cans within said recesses andbelow and in line with said openings.

The turntable and other mechanisms of the machine are operated by amotor l l. This motor rotates a sprocket l2 by a chain I3. To thesprocket, and axially aligned therewith, is a gear with a gear l5mounted on a shaft I3. On the shaft is a sprocket I1 which operates, bya chain I8, a sprocket i9 mounted on a shaft 23. O-n this shaft ismounted a crank 2|, which is connected by alink 22, to the end of arocker arm 23, pivoted on a shaft 24. On one end of the shaft 2d is aratchet 25 which is actuated by a pawl 26 pivotally mounted on therocker arm. 0n the opposite end of the shaft 24 'is mounted a bevel gear2l which meshes with another bevel gear 23, which is connected to the,lower vend of the turntable consisting of the star feed wheel 2 and thecutter disc 3. By such operation the turntable is rotatedintermittently. In line with one of the perforations of the cutter disc,that is, when the turntable is at rest, and preferably at the rearmostperforation, is a compressing cylinder 3i, which extends verticallyabove the cutter disc. This cylinder is supported in the manner statedby a suitable support, such as by supporting rods 32. The intermediateportion of this cylinder has an inlet opening 3l'ad at its rear side forreceiving the product to be packed through a tube 33 from a hopper 34.The and provides the discharge opening 3i".

In the cylinder is reciprocally mounted a plunger 35 which isreciprocated by a crosshead 33 supported on and guided by the rods 32.An adjusting screw 31 connects the piston tothe crosshead so that theposition of the piston may be readily adjusted relative to thecrosshead. From the `ends of the crosshead beyond the rods 32, extendsvtrunnions 35*ab which are pivotally connected by links 38 to crank pins332L of cranks 39, which are mounted on the opposite ends of the shaftIB. l

The hopper 3ftr is provided with a feed screw 4I at the lower portionand diverges upwardly to an open upper portion. This feed screw ispreferably rotated intermittently,'through gears 42, 43, and 44, by ashaft 45. This shaft has a sprocket 46 which is operated by a chain 41from a sprocket 43. The latter sprocket is mounted on the shaft 49 whichis connected to a shaft 53 gears 5| and 52. On the latter 54, mounted ona rocker arm 55, pivoted on the shaft 50. 'I'he free end of the arm isconnected by a link 56 to the crank pin 39a of one of the cranks. Inthis manner uniform rotation is transmitted intermittently to the feedscrew.

The gears 42 and 44 may be two series of step gears which may bevariously connected by an idler gear 43 for changing the speed of thefeed screw. That is, the small gear of the series 42 of the plunger, asstated, permlts the cutting operation of the cutting disc 33 withoutinterference by the plunger 35. As the turntable is robracket 63. tion,clear of which is reciprocally in a bearing 66a. On which is adapted tobe enmounted at its lower end the rod is a stop 66b means of a screw 68,downward movement varied.

The open track product which does may drop from the 4 for the cans,permits the not enter the can, or which iiakes. Diiculty has heretoforebeen encountered, when attempting to pack sh flakes in securinguniformity of Weight of the sh in consecutive cans. I have solved thisdiiculty by compressing the sh akes to a certain density be handled as asolid, and then a suitable oil, liquid, or flavoring, may be added abovethe product compressed in the can.

Though I have shown and described a particular construction,

pended claims.

I claim:

l. In a machine of the class described, a cylinder having a dischargeopening at one end inlet opening spaced backwardly from product feedingmeans communicating w1th the inlet opening of the cylinder, a

ing through the discharge opening, as the cutting means is moved by theconveyor.

2. In a machine of the class described, a cylinder by the conveyor.

4. In a machine of the class described, a cylinder having a dischargeopening at one end and an inlet opening spaced backwardly from said end,a product feeding means communicating With the inlet opening of thecylinder, a plunger reciprocally mounted in the cylinder and movabletherein from the inlet opening toward the discharge opening lbutterminating short of the latter opening, for compressing and forming inthe cylinder the product to be packed and forcing said compressedproduct therefrom, means at the discharge opening for supporting an openpacking can, and means at the discharge end o the cylinder for cuttingoff the portion of the compressed product extending through and beyondthe discharge opening.

5. In a machine of the class described, a cyl-` inder having a dischargeopening at one end and an inletopening spaced backwardly from said endaproduct feeding means communicating with the inlet opening of thecylinder, a plunger reciprocallyT mounted in the cylinder and movabletherein from the inlet opening toward the discharge opening butterminating short of the latter opening, for initially compressing andforming in the cylinder the product to be packed and forcing saidcompressed product therefrom, means at the discharge opening forsupporting anopen packing can, means at the discharge end of thecylinder for cutting off the product extending through and beyond thedischarge opening, and means for subsequently pressing the Whole of theupper portion of the product into the can below the upper rim thereofafter being placed therein by the plunger and cut off.
